TOC analysis:

• TC ( Total Carbon)
  The sum of organic bound and inorganically bound carbon present in water, including elemental carbon
• TIC (Total Inorganic Carbon)
  The sum of carbon present in the water,consisting of elemental carbon,total carbon dioxide, carbon monoxide, cyanide, cyanate, and thiocyanate.
  ( TOC instruments mostly register as TIC only the CO₂ originating from hydrogen carbonatess and carbonates.
• TOC ( Total Organic Carbon)
  The sum of organic carbon present in the water, bonded to dissolved or suspended matter. Cyanate, elemental carbon and thiocyanate will also be measured.
• DOC ( Dissolved Organic Carbon)
  The sum of organic carbon present in the water, originating from compounds which will pass a membrane filter of pore size of 0,45 micron. Cyanate, and thiocyanateare also measured.
• VOC , POC ( Volatile Organic Carbon)
  Under the condition of this method purgeable organic carbon (POC)
• NVOC , NPOC ( Non Volatile Organic Carbon)
  Under the condition of this method non-purgeable organic carbon (NPOC)
